tohoku earthquake magnitude

[105][106][107], Four days later on 11 April, another magnitude 7.1 Mw aftershock struck Fukushima, causing additional damage and killing a total of three people. Seismic stations in Iwate, Gunma, Saitama and Chiba Prefecture measured a lower 6, recording an upper 5 in Tokyo. A few cases of suicide are also included. [366][367] The earthquake was the fifth-strongest since 1900, and the seventh-largest in recorded history. [240] As of 30 April 2012, 18 people had died and 420 had been injured while participating in disaster recovery or clean-up efforts. [387], Also, following the earthquake, for the first time in Japanese history, the Emperor addressed the nation in a pre-recorded television broadcast.[388][389]. Kyodo News, "Survivors in trauma after life-changing nightmare day". [385], Atsushi Funahashi, director of Nuclear Nation notes that "when the overseas media was calling Fukushima a 'meltdown,' the Japanese government and media waited two months before admitting it. [181] Surges of up to 1 m (3 ft 3 in) hit Vancouver Island in Canada[179][failed verification] prompting some evacuations, and causing boats to be banned from the waters surrounding the island for 12 hours following the wave strike, leaving many island residents in the area without means of getting to work. The surface energy of the seismic waves from the earthquake was calculated to be 1.9×1017 joules,[84] which is nearly double that of the 9.1 Mw 2004 Indian Ocean earthquake and tsunami that killed 230,000 people. The M 7.6 subduction earthquake of 1896 created tsunami waves as high 38 m and caused 27,000 fatalities. [123][124][125] Chile's Pacific coast, one of the furthest from Japan at about 17,000 kilometres (11,000 mi) away, was struck by waves 2 metres (6.6 ft) high,[126][127][128] compared with an estimated wave height of 38.9 metres (128 ft) at Omoe peninsula, Miyako city, Japan. Narita and Haneda Airport both briefly suspended operations after the quake, but suffered little damage and reopened within 24 hours. The center, which houses a control room for part of the International Space Station, was shut down and some damage was reported. [271] Voluntary reductions in electricity use by consumers in the Kanto area helped reduce the predicted frequency and duration of the blackouts. In 2001 it was reckoned that there was a high likelihood of a large tsunami hitting the Sendai plain as more than 1,100 years had then elapsed. 1. [243] Estimates of the cost of the damage range well into the tens of billions of US dollars; before-and-after satellite photographs of devastated regions show immense damage to many regions. [110], As of 16 March 2012 aftershocks continued, totaling 1887 events over magnitude 4.0; a regularly updated map showing all shocks of magnitude 4.5 and above near or off the east coast of Honshu in the last seven days[111] showed over 20 events. [5], The main earthquake was preceded by a number of large foreshocks, with hundreds of aftershocks reported. While the Japan Trench was known for creating large quakes, it had not been expected to generate quakes above an 8.0 magnitude. [263] On 12 March 252 dams were inspected and it was discovered that six embankment dams had shallow cracks on their crests. Railway operators gradually increased capacity over the next few days, until running at approximately 80% capacity by 17 March and relieving the worst of the passenger congestion. [257] The Tōkaidō Shinkansen resumed limited service late in the day and was back to its normal schedule by the next day, while the Jōetsu and Nagano Shinkansen resumed services late on 12 March. The major earthquake and tsunami occurred in Tohoku, Japan on March 11th, 2011 at 2:46pm. The tsunami resulted in over 340,000 displaced people in the Tōhoku region, and shortages of food, water, shelter, medicine, and fuel for survivors. Date of the Earthquake. It was the most powerful earthquake ever recorded in Japan, and the fourth most powerful earthquake in the world since modern record-keeping began in 1900. The timing of moment magnitude nine (M w9) -class earthquakes appears to be controlled by multiple preceding slip events, smaller earthquakes [167][168] At Tarō, Iwate, the tsunami reached a height of 37.9 metres (124 ft) up the slope of a mountain some 200 metres (660 ft) away from the coastline. The quake hit at 2.46pm (5.45am GMT), about 6 miles below sea level and 78 miles off the east coast. Most tsunamis, like the one that formed off Tohoku, are triggered by underwater tectonic activity, such as earthquakes and volcanic eruptions. By Elisabeth Nadin Ph.D., University of Alaska Fairbanks [324] The plant was shut down as a precaution. The temblor also shortened the length of a day by about a microsecond. Because of the unquestioning nature of most Japanese media to hold to the "party line", many Japanese mid-level officials and experts spoke to foreign media to get their opinions and observations publicized. Japan experienced over 1,000 aftershocks since the earthquake, with 80 registering over magnitude 6.0 Mw and several of which have been over magnitude 7.0 Mw. Aid organizations both in Japan and worldwide also responded, with the Japanese Red Cross reporting $1 billion in donations. It could take months or years to learn how damaging the release of dangerous isotopes has been to human health and food supplies, and to the surrounding countryside. If the initial estimate is confirmed, it will be the fifth largest earthquake in recorded history. [285], An analyst estimates that consumption of various types of oil may increase by as much as 300,000 barrels (48,000 m3) per day (as well as LNG), as back-up power plants burning fossil fuels try to compensate for the loss of 11 GW of Japan's nuclear power capacity. [212] As of March 2012, Japanese police data showed that 70% of the 3,279 still missing were aged 60 or over, all found, including 893 in their 70s and 577 in their 80s. [294], In addition to refining and storage, several power plants were damaged. [68] Aftershocks follow Omori's law, which states that the rate of aftershocks declines with the reciprocal of the time since the main quake. The 2011 Tōhoku earthquake and tsunami has been assigned GLIDE identifier EQ-2011-000028-JPN by the Asian Disaster Reduction Center. [138] A 4-metre-high (13 ft) tsunami hit Iwate Prefecture. YASAL UYARI: Yayınlanan yazılı haber, fotoğraf ve videonun tüm hakları İlke Haber Ajansı A.Ş. [352] Immediately after the earthquake cellular communication was jammed across much of Japan due to a surge of network activity. [392] However, occurring as it did 373 km (232 mi) north east of Tokyo, the Tōhoku earthquake came as a surprise to seismologists. [158] Near Ōarai, people captured images of a huge whirlpool that had been generated by the tsunami. The Japanese government's response to the earthquake, the efforts of Japanese citizens to help with recovery, and the disaster itself have inspired many works from Japanese creators. [274], To help alleviate the shortage, three steel manufacturers in the Kanto region contributed electricity produced by their in-house conventional power stations to TEPCO for distribution to the general public. maximum magnitude size for Tohoku area (around 7.7) was proposed in the official hazard map (Geller, 2011; Stein et al. [377], According to Japan's foreign ministry, 116 countries and 28 international organizations offered assistance. The loss of electrical power halted cooling systems, causing heat to build up. [228] Among them were two English teachers from the United States affiliated with the Japan Exchange and Teaching Program;[229] a Canadian missionary in Shiogama;[230] and citizens of China, North and South Korea, Taiwan, Pakistan and the Philippines. Cargo contained yellowtail jack fish, a species that lives off the coast of Japan, still alive. [112], As of 11 March 2016[update] there had been 869 aftershocks of 5.0 Mw or greater, 118 of 6.0 Mw or greater, and 9 over 7.0 Mw as reported by the Japanese Meteorological Agency. [147][148] Also largely destroyed was Rikuzentakata, where the tsunami was three stories high. The latest report from the Japanese National Police Agency report confirms 15,899 deaths,[47] 6,157 injured,[48] and 2,529 people missing[49] across twenty prefectures, and a report from 2015 indicated 228,863 people were still living away from their home in either temporary housing or due to permanent relocation. The M 8.6 earthquake of March 2, 1933, produced tsunami waves as high as 29 m on the Sanriku Coast and caused more than 3,000 fatalities. Many sections of Tōhoku Expressway serving northern Japan were damaged. On 11 March 2011, a massive 9.0 earthquake occurred off the Japanese coastline at 14:46. Calculations at NASA's Jet Propulsion Laboratory determined that the Earth's rotation was changed by the earthquake to the point where the days are now 1.8 microseconds shorter.[102]. [115][116] The warning for the general public was delivered about 8 seconds after the first P wave was detected, or about 31 seconds after the earthquake occurred.

Öncüoğlu Sitesi A/Blok No:1 Of those who didn't heed the warning, 49% were hit by the water. [296] Higashidōri, also on the northeast coast, was already shut down for a periodic inspection. [365], JAXA (Japan Aerospace Exploration Agency) evacuated the Tsukuba Space Center in Tsukuba, Ibaraki. This earthquake occurred where the Pacific Plate is subducting under the plate beneath northern Honshu. In the fall of 2016 Japan's National Research Institute for Earth Science and Disaster Resilience (NIED; Japanese abbreviation, Bosai Kaken; full name Bousai Kagaku Gijutsu Kenkyusho) launched the online interactive "Disaster Chronology Map for Japan, 416–2013" (map labels in Japanese) to display in visual form the location, disaster time, and date across the islands. [11][64] On 11 July 2016, the USGS further upgraded the earthquake to 9.1. Two days of seismic activity made available by the IRIS Consortium were compressed into two minutes of sound. The thousands of bodies, however, exceeded the capacity of available crematoriums and morgues, many of them damaged,[233][234] and there were shortages of both kerosene—each cremation requires 50 litres—and dry ice for preservation. [353] Internet services were largely unaffected in areas where basic infrastructure remained, despite the earthquake having damaged portions of several undersea cable systems landing in the affected regions; these systems were able to reroute around affected segments onto redundant links. [58] The World Bank's estimated economic cost was US$235 billion, making it the costliest natural disaster in history. [50], A report by the National Police Agency of Japan on 10 September 2018 listed 121,778 buildings as "total collapsed", with a further 280,926 buildings "half collapsed", and another 699,180 buildings "partially damaged". This motivated government researchers to look into other ways the earthquake may have had large scale effects on the planet. An official in the city's government trash disposal department estimated that it would take three years to empty these sites. [269] TEPCO, which normally provides approximately 40 GW of electricity, announced that it could only provide about 30 GW, because 40% of the electricity used in the greater Tokyo area was supplied by reactors in the Niigata and Fukushima prefectures. [285] Workers were evacuated,[291] but tsunami warnings hindered efforts to extinguish the fire until 14 March, when officials planned to do so. [278] The peak electricity consumption within TEP's area was 12.46GW during the 2011 summer, 3.11GW (20%) less than the peak consumption in the previous year, and the overall consumption have been reduced by 11% in July with 17% in August compared to previous year. The tsunami propagated throughout the Pacific Ocean region reaching the entire Pacific coast of North and South America from Alaska to Chile.
